This is a class for the newcomer, althought it is good to have some experience working with PC's. It is not nessesary to have

knowledge of computer network's and IP.

The class will teach the basic understanding of how VoIP (Internet based telephony)

works in Theory and practise. Class is mixed 40% Theory and 60% practise. All exercises and labs are done in realistic real

world network enviroments with the latest most stable available technology.

During the class you will learn howto plan you VoIP network.

You will also install learn howto configure and install VoIP equipment, first in your controlled enviroment. After you learnmore during the class you will head common real life situations similar to your customers network enviroment. You willlearn to avoid common pitfalls in forehand. Also class will learn you howto find and correct most common errors

that arrives during installation and in production.

All classes are builtof theory blocks, and practise blocks.

Slides and whiteboard are used by theachers, studends have one PC each

plus copy of slides and classroom books.

11. Exam and Certification

1. Theory Physical network enviroment

How IP and its transport layers works.

a) Data link physical (cables, connectors, switches and bridges)

Different kind of networks: bus, star, ring, mesh.

b) Network (the internet layer ontop of all cables)

c) Transport (howto transport data over internet)

d) Application (what you want to do with the data, voice, email, etc.)

e) What is bandwith/broadband ADSL/Cable/Analog modem?

f) Wireless networks WiFi and OFDM.

g) Internet over PowerLine

2. Practise Physical network enviroment wiring the VoIP devices

Physically connect PC's and Adapters to router and switch.

Purpose is to learn getting the physical network correctly connected.

a) Identify and understand difference between bridge, switch, router.

b) Identify different cables like TP strait and crossover, coax and fibre.

c) Making TP cables strait and crossover.

d) Identify cable trouble. Find ports, what is WAN and LAN ports.

e) What the LED'S mean ? Link up/Link down

f) Experience effects of bandwith problems.

g) Looking at wireless technology,

Setting up a small WiFi lab net and connect WiPhone to it.

Securing the WiFi with WEP and SSID.

h) Looking at Internet over powerline

Setting up a two PLM and connecting phones to it.

28

Securing PowerLine distributed traffic.

3. Theory TCP/IP

Basic IP protocols and their fundamental functions.

Purpose is to have understanding on TCP/IP in order to

be able configuring devices and avoid problems.

a) arp (binding datalink physical to ip addresses)

b) ip (addressing, public and private)

c) icmp (ping, traceroute, latency)

d) tcp / udp (data transport systems)

e) Common port's (Services and application connections)

f) dhcp (Automatic configuration delivery to clients from servers)

h) dns (purpose of nameserver, what is you logical name ?)

i) Plug and Play

j) Quality of Service.

4. Practise TCP/IP connecting VoIP devices

In this exercise's you will learn how to configure your network equipment

VoIP, Voice over IP has become very popular but few really understand how to make it in practise lifeand even less success stories. This class material and content is based on our knowledge andexperience of building large VoIP network, and make is success story.

Learning by doing

This class is supposed for systems integrator/network technicians who will learn how IP-basedtelephony works into the deep, as well as business aspects for companies intended to set-up VoIP.This is done by mixing theory with practise in all steps. The class is balanced almost 50/50 when itcomes to theory and practise.

Class focus

The focus is on how to construct and set-up the infrastructure with gatekeepers and gateways, andinstall end users equipment in various environmentsbehind firewalls and dhcp/nat-routers. Also welook on how to build and provide IP telephony with wireless network environments like 802.11abg.

Migrating telecon and datacom

We learn how classical telephony systems such as POTS and GSM can be integrated/interconnectedand how to add various services to gain extra functionality like IVR and also video and hi-fi radio.

Participants must have experience of working with computers as advanced user and

basic knowledgeof datacom and telecom. Also basic knowledge of TCP/IP is necessary. Special introductions class willbe held in front of this class if necessary.

Planning

The entire class is one week full time 09.00 to 16.45. Days are divided by lunch,before lunch westudy theory and after lunch we practise with exercises and labs. There are after class doings for theone who like.

Books and class material

We have our own class material which consists of a study folder which contains most, in additiontothis we also have a bookIP Telephony with H.323ISBN: 0471393436 John Wiley & Sons Inc

(Internet Communications Using SIPISBN: 0471413992

John Wiley & Sons Inc ).In addition to thebooks we also have a lab with various IP phones and routers as well wireless equipment and PC’s.
